u-drill 4001F
The Kverneland u-drill – the universal seed drill combination
The trailed universal seed drill combinations carries out seedbed preparation, levelling, reconsolidation and seeding in one pass.
Highlights
High speed operation (10 – 18km/h) Perfect seed placement Modular frame concept for flexible adjustment Fully ISOBUS compatible Easy handling and maintenanceDescription
The u-drill is a trailed seed combination to carry out seedbed preparation, levelling, reconsolidation and seeding in one pass. The folding models of the Kverneland u-drill are available in 4.0m and 6.0m working width. Focus in design has been especially given to high-speed operation (10-18km/h) whilst ensuring a perfect seed placement.
With the Kverneland CD-coulter, two different row widths are possible: 12.5cm and 16.7cm row distance. The hopper with a capacity of 3,000 litres can be easily filled by big bags, front loader or telescopic handler.
The u-drill is extremely user-friendly: Fully ISOBUS compatible, the driver is in full control of all data. The u-drill is ready for GEOCONTROL in order to control application rate and half-width shut-off.
Features
Step 1: Level the soil
For the best possible preparation, the front tyre packer levels the soil, crushes large clods and thus paves the way for the optimum depth control of the following tools. The front tyre packer has a diameter of 800mm. When it is not needed, it can be lifted hydraulically, simply by pushing a button..
Step 2: Prepare the seedbed
The disc harrow section consists of two rows of aggressively pitched conical discs. The discs are 5mm thick and hardened for long life. Thanks to their conical shape, the cutting angle remains constant. The high rotation speed ensures an excellent cutting quality over the entire working width. The distance between the sowing rows can be 12.5or 16.7cm.
The MD disc section consists of two rows of straight waved discs. The MD disc have been designed for vertical penetration through the flutes. The blade keeps turning, penetrating and cutting even in the most challenging conditions. A seedbed is created only in stripes of 3 to 5 cm in width, in which the seed is placed by the CD coulter.
The MD disc section is available for machines with 16.7 cm row distance and with the u-drill plus in combination with double entry fertiliser injection.
Step 3: First pack, then seed
For perfect depth control of the coulters and an optimum seed-to-soil contact providing excellent capillary action, the loosened soil is re-compacted by a large tyre packer. The large tyre diameter of 900mm significantly reduces the tractive power required by the machine and thus ensures a consistently good work result.
Step 4: Drill and pack at constant seeding depth
The narrow profile of the coulters with their slightly offset steel discs allow easy penetration into the soil. Thus, little pressure is required at this point with only little soil being displaced. The coulter pressure of 100kg can, therefore, be primarily used for the pressing by the integrated press wheels. The result: a uniform seeding depth even at high working speeds! The seeding depth and the coulter pressure can be centrally controlled by the push of a button from the tractor cab – this saves additional time.
The stable depth control and the pressing of the seed produce a capillary system in the soil that ensures access to water and excellent germination
Step 5: Closing
Harrowing the soil completes the drilling. S-shaped or finger harrows ensure an optimum covering of the seeds. The working intensity can be set by the stepless pressure adjustment and at three different angles. To prevent damage to the harrow when reversing, it is equipped with an effective reversing device.
The u-drill comes with a fully automated headland management system. This saves the driver lots of time and eases the operation. Using just one button, the driver can initiate a headland sequence with wheels, discs and coulter bar all capable of automatic operation in timed stages. The lifting sequence starting with the disc section ensures a constant depth control until the headland.
As the headland sequence starts, the metering device stops automatically – avoiding double seeding. The seed hoses are empty at the headland. This saves up to 5% of seed.
The driver can concentrate on steering the machine and the correct operation. In addition double and/or missed seeding is prevented. With headland management the job can be done more quickly, precisely and efficiently. The drill requires only one double-acting spool to operate.
- ELDOS is electric driven by e-bas and e-com, the e-com edition is fully ISOBUS compatible, e-bas works as stand alone controlled system.
- GEOCONTROL by GPS signal is possible which avoids double seeding.
- Special sensors ensure functionality from the tractor cab.
- Five standard rotors are delivered: for fine and large seeds or fertiliser.
- The exchange of the rotors is quickly and easily done without any tools.
- Application rates from 1 to 400kg/ha are possible (depending on working speed and width).
- The metering device is always easily accessible.
Calibration
- Very simple calibration test due to the separate seed guidance.
- A remote control allows the driver to operate the calibration process at the metering device.
- No gear has to be adjusted. The driver simply enters the desired values into the terminal, presses one button to start at the metering device and that’s it.
- The calibration is done automatically.
- A calibration flap with an integrated gate prevents any seed from dropping into the hose.
